I just bought my first AR-15. It's a S&W M&P 15 Flat Top. I purchased the rear handle type sight and the standard A2 front sight separate. Both fit well on the picatinny rail. In short, rear sight all the way up, front sight all the way down, it shoots 12" low at 25 yards. I compared it to a Double Star flat top and learned that the top of the rail (gas block) for the front sight is 1/4" +/- higher than the Double Star. That will explain the low elevation on the shot. My question is, what kind of picatinny rail front sight will suit my application? I wanted the A2 style/look if possible. Any suggestions or references appreciated.
Thanks in advance.
